Here's the most essential music theory concept for guitarists - musical keys. This knowledge explains why certain chords sound great together and helps you understand song structure across all genres.
Key of E major: using E, A, and D major chords in songs like "Back in Black"
Key of A major: how "Wild Thing" and "Chasing Cars" use A, D, and E combinations
Key of G major: incorporating minor chords with G, C, D, and E minor/A minor
How to identify a song's key by listening for the "home" chord
Why the same chords can work in different keys (like Sweet Home Alabama vs Brown Eyed Girl)
You'll see that this isn't just theory - it's practical knowledge that explains why you've been practicing certain chord changes together. Understanding keys helps you learn songs faster and even write your own music using chords that naturally sound good together.
